ARTICLE OF IANUFACTURE FOB ENDING RADIATORS.

Application filed larch 8, 1926. Serial No. 93,094.

' My invention relates to the repairing and sealing of leaks in rathators or clrculating systems for road vehicles and in similar apparatus. Y

The object of the invention generally is a novel self-contained leak sea-ling composition or mixture for radiators and similar devices and in the form of an article of manufacture which is capable of securely sealing and plugging leaks therein with marked rapidity and certainty, and moreover, with only the attention and labor required for depositing the article into the faulty radiator. A further object is an article of this character which is capable of retaining indefinitely its original form, quality and character, unimpaired under ordinary temperature, atmospheric and distributing conditions, but which upon introduction into a faulty radiator is capable of quick dissolution and thorough and intimate dissemination throughout the water contained therein, enabling the sealing materials to reach in a very short time the remotest and most inaccessible leaks to form closures therefor. A still further object is a sealing device of this character and capable of forming closures which resist disintegration to a marked degree and are practically permanent under the ordinary conditions experienced in radiators for motor vehicles. To these ends I have devised a composite sealing article of small compass including an inner body which forms one part of the sealing mixture or compound and an outer enclosing part which forms a Supplementary part thereof, the latter being of a character to perform the combined.

functions of a housing or retaining casing for the inner part and preserving its form, quality and character until introduction into the faulty apparatus, but being capable of ready solution and intimate mixture with the innerpart in the water contained therein to expedite and facilitate the forming of closures for the leaks I have obtained particularly good results by-combining' with the outer soluble co onent an inner body containing-vegetable bers, the inner body being capable of solution and uniform distribution and suspension throughout the water contained in the radiator and functioning with the solution of the outer housmg component. to quickly bridge and close up the leaks when carried there by the cirhardness at ordinary temperatures and under normal atmospheric conditions to be. self-supporting and preservative of the form.

and quality of the article but readily and quickly soluble and miscible with the inner part in the water contained in the leaky radiator. I have found that an outer housing or enclosing casing of gelatin possesses thedesired characteristics to a marked degree. It has the strength, toughness, rigidity and preservative character required un- (lcr normal temperature and atmospheric conditions. is capable of a quick solution in the water. and readily mixes upon solution with the vegetable fiber mixture to accelerate the concentration of the composition at the leaks and to 'form closing walls therefor. It is of a character to dissolve and form an intimate mixturewith the inner part of the composition without the necessity of grinding or special treatment therewith. and moreover I have found that a' composition or mixture of gelatin and vegetable fibers is capable of forming better and more rapid closures than is the case with any prior sealing compound with which I am familiar. Gelatin, therefore, is the present preferred material and constituent of the composition forming the enclosed housing or casing for the composite self-contained unit. since it is not only harmless and non-injurious to the metal of the radiator. but forms an important constituent of the composite com table fibers but it is preferable to use a vegetable fiber whose specific gravity approximates that of the fluid contained in the leaky vessel, such for example as cotton linters. The inner part of the composition. in addition to the vegetable fiber material, may of course contain other constituents such for example as a starchy material like cornstarch, the latter serving as a binder and a filler, and it is understood that the constituents of both the soluble outer and inner parts of the composition may be varied within the limits defined in the claims annexed hereto without departing from the invention.

My self-contained but soluble composition or mixture may be formed into. various and sundry shapes, as for example in the form of a cartridge which happens to be of a convenient shape for introduction'into the ordinary filling opening of automobile radiators. In Fig. 1 I have indicated such an embodiment of my invention in sideele vation, and in Fig. 2 I haveshown a crosssection thereof where'in the normally selfsupporting but readily soluble component of the composition and forming the housing for the unit is designated by the numeral 1 and the inner portion of the composition including the vegetable fibrous material is designated by the numeral 2. A convenient method of forming the article is tofinely grind or pulverize the vegetable fibrous mixture'2 and form the housing 1 into two telef scopically arranged parts whereby they may be filled with the portion 2 of the composition and closed upon each other in capsule fashion, or the portion 2 may be formed into an adhering mass and enclosed in the housin 1 in any suitable manner, I have found that in a cartridge of approximately 2-1/2 to 3 inches length and 1 inch diameter, a wall thickness of 1/64 to 1/32 inches is ample to afiord the required housing or casin strength and at the same time contain su cient soluble outer component to properly function with the inner mixture to effect the closures with the desired rapidity and certainty. The only attention and labor required formendi'ng a leaky radiator or other faulty vessel is to deposit the article bodily therein, the contained waterv quickly dissolving the gelatin outer component and disintegrating the inner body to form an intimate mixture thereof. The warmer the water the more quickly the disas by dipping.

solution takes place with the consequent expediting of the forming of the closures.

My invention, as above described, is par ticularly adapted to the sealing and mendingof leaks in automobile radiators, but may of course be also used to advantage in the sealing of leaks in stationary heating and cooling devices or circulating systems.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. As an article of manufacture, a selfcontainedreadily soluble, disintegrable, and miscible leak sealing device for radiators and the like consistin of'an inner body containing vegetable fibrous materal and an outer self-supporting component enclosing the inner body, the outer component being capable of maintaining and preserving the form, quality and character of the device underordinary temperature and atmospheric conditions, but capable of ready solution and intimate mixture with the inner body in water to form closures for the leaks upon being conveyed thereto.

2. A an article of manufacture, a composite self-contained sealing device for radiators and the like including an inner part and anvouter component in the form of a readily soluble and miscible self-supporting housing enclosing the inner part, the two capable upon solution of the outer component of functioning conjointly to form closures for the leaks.

3. As an article of manufacture, a selfcontained soluble disintegrable and miscible sealing device consisting of an inner body containing a finely ground vegetable fibrous material and an outer self-supporting component of gelatin enclosing said inner body.

4. An article of manufacture of the character described including a body of sealing I have signed my
